Network policy logs

Hi,
I have a “- action: Log” in one of my Calico policies but not sure where to look for generated logs. The only thing the doc says is that it is logged to syslog without any other info. What do the logs look like and what should I look for? I’ve used journalctl but not sure what to look for. Any hepl is appreciated. Thanks!

Syslog is a standard linux logging system. Its not possible to give prescriptive advice on where to find the logs because it depends what Linux distro you’re using and how its configured.

Here’s an overview: Syslog - Definition and Details

However, most linux distros by default have a syslog server listening on localhost that writes to /var/log/syslog or /var/log/messages

Thanks, the question wasn’t where to find the sys logs, it was what to look for in the logs. In other words, what are some identifiers of a message logged by Calico? There are thousands of messages logged by various and simply reading them line by line isn’t practical.

Here’s an example (from simply tailing syslog while curling from pod-pod):

@lwr20, Thank you very much!
